WILLIAM H. DAUGHERTY, OF JASONVILLE, INDIANA.

CAR-WHEEL.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed January 4, 1910. Serial No. 533,432.

To all whom it may concern:

Be it known that I, VILLIAM H. DAUGH- nnrr, citizen of the United States, residing at Jasonville, in thc county of Greene and State of Indiana, have invented certain new and useful Improvements in Car-lheels, of which the following is a specification.

This invention relates to journal bearings and refers particularly to a device especially adaptable to railway cars of light construction.

The invention has for an object the provision of an improved journal bearing and wheel for interfitting with the same whereby the wheel may be readily detached without removing the car from the track or of necessitating the complete withdrawal of the axle which supports the Wheel.

The invention has for another object the provision of a journal bearing which embodies strength and durability, as well as simplicity` in construction, so as to produce a device of this nature which is applicable to mine cars where the same are subjected to severe usage, and wherein it is necessary to provide means for detaching the wheels from the car without conveying the same to a general place for repairs.

For a full understanding of the invention reference is to be had to the following` description and accompanying drawings in which Figure 1 is a transverse section through a mine car disclosing the improved journal bearing and hub in section and attached to the same. Fig. 2 is a detailed sectional view of the journal bearing and hub in detached position and ready to be assembled, and Fig. 3 is a detailed perspective view of the bearing and the hub of the wheel detached from one another.,

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

Referring to the drawing the numeral 10 designates the body of the mine car which is provided with the improved ournal bearing consisting of the boxing 11 which is supported adjacent one end of the car 10, and at one side thereof through the medium of a web 12. The web 12 is preferably cast integral with the boxing 11 and extends upwardly from the outer end thereof for engagement against the outer side of the body 10. Bolts or rivets 13 are engaged through the web 12 and and the side of the body 10 to support the boxing 11 in position.

The inner end of the boxing 11 is provided with an annular bead 11 which provides a groove 15 for the reception of a retaining strap 1G for engagement in the groove 15 between the bead 14 and the outer end of the boxing 11 to prevent the lateral play of the boxing incident to the jarring of the same when the body 10 is in motion. The strap 1G is suitably secured against the bottom of the body 10. The outer end of the boxing 11 is provided with an overhanging flange 17 which is extended outwardly therefrom and of the formation of a housing of an inverted U-construction to form a channel 18 within the inner wall of the same. The upper portion of the flange 17 is concentrically disposed with relation to the passage 19 provided through the boxing 11 and in which is inserted the outer end of an axle 20.

The improved hub, which is designated as 21 on the drawing, and which is adapted for engagement with the boxing 11, comprises the usual hub struct-ure with an inwardly extended and integrally formed collar 23 having a diameter corresponding to the inner face of the flange 17, whereby the collar 23 is permitted to rotate freely and is prevented from lateral vibration therein. The inner end of the collar 23 is provided with a flange 24C which engages loosely in the channel 1S for the purpose of preventing the displacement of the collar 23 from the fiange 17.

It will be observed from Fig. 1 that the axle terminates at a point centrally within the hub 21 to admit of the positioning of a threaded plug 25 in the outer end of the hub 21 which is correspondingly threaded to retain the plug 25 in position. An angular head 26 is formed upon the outer end of the plug 25 for the reception of a suitable wrench, or like implement, by means of which the plug 25 is rotated to withdraw the same from the hub 21.

In the operation of the device, when it is desired to withdraw a wheel from the body portion, the body 10 is raised slightly from the ground whereupon the plug 25 is re- .moved from the hub 21 and the axle 20 is driven inwardly through the collar 23 to a point beyond the inner face of the flange 24.

This positioning of the axle 20 admits ofv the downward movement of the collar 23 in the fiange 17 to withdraw the flange 24 of the collar 23 from the channel 18 and to thereby admit of the removal of the wheel 22. To etliect this result, it is of course, necessary to remove the plug 25 from the opposite hub 2l to admit of the longitudinal movement of the axle 2O through the opposite boxing ll.

Having thus described the invention what is claimed as new is l. A journal bearing including a cylindrical boxing having an enlarged and overhanging flange at its outer end, the flange being interrupted at its lower side, a hub engaged against the box, an annular flange formed on the inner end of said hub for interlocking engagement with the overhanging flange, an axle loosely engaging through said boxing and said hub when registered to secure the same together, and a detachable plug carried in the outer end of said hub to retain the axle from displacement.

2. A journal bearing including a boxing having a web adjacent its outer end to seat against the side of a supporting body, and

having an overhanging flange outwardly of the web and being open at its lower side, said boxing also having spaced beads to provide a groove, a retaining strap seated in the groove and carried by the supporting inember to secure the boxing thereto, a hub positioned against the outer end of the boxing, an annular flange formed over the inner end of said hub for interlocking engagement with the overhanging flange, an axle loosely engaging through said boxing and said hub when registered to secure the same together, and a detachable plug carried in the outer end of said hub to retain the axle from displacement.

In testimony whereof I affix my signature in presence of two witnesses.
